This program computes covariance information for the non­-stationary noise of the KBR antenna offset correction (AOC)
from the orientation covariance matrices provided in Level-1B products via variance propagation.
By using the output <a class="groops-class" href="fileFormat_matrix.html">outputfileSatelliteTrackingCovariance</a> in <a class="groops-program" href="PreprocessingSst.html">PreprocessingSst</a>,
noise model distinguishes between the stationary noise of ranging observations and the non­stationary AOC noise.</p><p>The covariances are derived from the partial derivative of the AOC w.r.t. the roll/pitch/yaw rotations
and star camera covariances <a class="groops-class" href="fileFormat_matrix.html">inputfileScaCovariance1</a> and <a class="groops-class" href="fileFormat_matrix.html">inputfileScaCovariance2</a>.</p><p>The covariances for the range-rates and range-acceleration are computed by differentiating
an interpolation polynomial of degree <strong class="groops-config-element">interpolationDegree</strong>.
